Complain of the service given

Absa gives the poorest service ever, i went to absa on the 25 th of October to activate my credit card, i was asked to bring my proof of residence. I then brought it on the 31 October. I was told that my stamp is not clear, u then went to municipality to stamp it, to my surprise they accepted it and did whatever was supposed to be done. I then left later when I tried to use my card it did not work. On the 1 November i went to absa again, they told me they want a proof of residence, i then gave them the one of yesterday, then they tell me they want a original letter with a original signature of the ward Councillor. I asked them why they did not tell me yesterday. No answer. I then left went to fetch the electricity bill that we get from the municipality, which they send us via email. Take it to absa, then they tell me they want a stamp on it. Absa service is terrible. They need to train their staff to be competent. U can not turn the customer 3 times before you can service them. Where is customer service absa????
